UNITED STATES PATENT OFFICE.

STEPHEN E. AMBLER, OF BROOKLYN, NEW YORK.

Specification forming part of Letters Patent No. 5 [,678, dated December 26, 1865.

To all Iwhom it may concern:

Beit known that I, STEPHEN F. AMBLER, county, and State of New York, have invented, made, and applied to use a new and Improved Ore-Separator.;

and I do declare' the fol-lowing to Vbe a "full, clear, and correct descriptionof the same, ref erence being had to the accompanying drawings, making a part of this specification', and to the letters of reference'marked thereon, in whichi Figure 1 is aperspective view of my improved ore-separator; Fig. 2, a .vertical cut section `of the same; Fig. 3, aview of the perforated tubes .F and, Scrapers E Fig. 4, a top view ofthe sieve Gr` employed, showing perforated tubes F-and scrapers .E -placed below the same; Fig. 5, a detached view, showingthe arms L, agita tors m and knives.

'In t' e drwin'gsike parts of the invention' A aredcsignated by the same letters of reference. The natu'reof my invention consists in the construction and operation of an ore-separator, ,as -hereinafter described. To enable those skilled in the arts to make and use my invention, I will speak of the con-I struction and operation ofthe same.

A Avshow a trame-work for supporting-the operating parts of my improved apparatus.

Otis a .hollow verticalv shaft, stepped at. c withinthe basin B. This shaft C may be made of rclal, and is provided at its lower end with the hub D, which hub D supports the concen-V trating-scrapers E, and into which hub D, connecting directly with the shaft C, are inserted thegbranch tubes F.

5E. show a series, attached to the hub D, and F a series'of branch tubes, provided with the perforationsinserted into the .hub D and connecting directly with the shaft C.

G shows a wire sieve ort-screen, by.tl1\e frame H;

Il is an outside .waste-basin, the space Abetween the outer, g, and inner, h, rims o which forms a reservoir, t, for the waste sand. r

J isa scraper attached to one .of `the arms supported Y L, and .inciting with the same.

provided with an opening,-v

-of concentrating-Scrapers' into the sieve at or near its center by means of a hopper' or otherwise. Water'is then introduced into the vertical hollow shaft C,which shaft C is caused to4 revolve, carrying-with it the agitators m, scrapers E, and hollow tubes F. 'The water introduced descends the shaft C, and,being discharged through the branch tubes F, is forced through the sieve G by the pressure of the water above. As the water is forced' through the'sieve G" it permeates the' ore, separating t-he sandv therefrom and carrying it(the sand) over the inner rim, h, of the waste-basin I into the reservoir t', while the ore passes through the sieve G into the basin B.

, In order to facilitate the separation of the ore and sand and prevent the formation of channels, I employ'the agitatorsm and knives a, attached to thearms L and revolving with the shaft C, while, in order that the reservoiri may be relieved of the sand, the scraper J is employed and carriesl the sand tothe opening K, whenceit is .discharged. As theore passes through the sieve or'screeu G into the basinB the concentrating-Scrapers E, attached to the hub D and revolving with the shaft C, concen' trate or collect and carry-the ore. to the opening i), whence it is discharged into avat or tank, from which it may be removed at pleasure.

The advantages of my invention are that by the use' of the brauch tubes and agitators, in combination with the hollow shaft, a more per- 'fect dii'usion of the water is effected, thus preventing the formation of channels; as the sieve-orfscreen remains stationary, it is less liable to-wcarout'anlneed replacing; thatb`y the use of the concentrating-Scrapers ,the ore is thoroughly removedfrom the basin B,thus economiaing time and labor; and, finally, that by the combined operatiomof the various parts of the apparatus the process of separating the 'ore is made a continuous one-that is to say, that the operator is not compelled every ten or ii'fteen minutes to stop the apparatus to remove tubes F, arranged and operated as shown, for

the sand and ore by hand, but that this operthe purpose described.

ation is 'effected by my apparatus itself. 2. In combination with the same, the scrap- Havig thus described my invention, what ers E, arranged and operated in the manner I claim as new, and desire to secure by Letdescribed, and for the purpose specl'ed.
